Desmodur RE, inozivikanwawo seCAS 2422-91-5, inogoneka uye inoshandiswa zvakanyanya. Nekuda kwekuita kwayo kwakanakisa uye zvakanakira, yakashandiswa zvakanyanya mumaindasitiri akasiyana. Muchinyorwa chino, isu tinoongorora mashandisirwo eDesmodur uye toona kuti nei ichinyanya kufarirwa nevagadziri.
Desmodur RE ndeyemhuri yeanonhuwirira diisocyanates, makomisheni anoshandiswa zvakanyanya mukugadzira polyurethane coatings, adhesives uye elastomers. Iyo yero yakareruka kune amber fluid ine musanganiswa wemasomeri ane akafanana makemikari zvimiro. Chinhu chikuru cheDesmodur RE i toluene diisocyanate (TDI), iyo inoshandiswa zvakanyanya mukugadzirwa kwe polyurethane foam.
Imwe yemashandisirwo makuru eDesmodur REiri mukugadzirwa kwe polyurethane coatings. Polyurethane coatings inopa yakanakisa dziviriro kubva mukuora, mamiriro ekunze uye abrasion. Ivo vanozivikanwa nekusimba kwazvo uye kuita kwakanakisa munzvimbo dzakaoma. Desmodur RE chinhu chakakosha mune aya maumbirwo ekugadzira, achivapa kuwedzera kuoma, kunamatira uye makemikari kuramba.
Chimwe chakakosha kushandiswa kweDesmodur RE kugadzirwa kwepolyurethane adhesives. Polyurethane adhesives anoshandiswa zvakanyanya mumaindasitiri emotokari, ekuvaka uye fenicha nekuda kwesimba ravo repamusoro rebhondi uye kuita zvakasiyana. Desmodur RE inokwidziridza kusimba kwechisungo che polyurethane adhesives, ichivabvumira kunamatira kune akasiyana substrates sesimbi, plastiki nehuni. Izvi zvinoita kuti ive yakanaka kune lamination, bonding uye kuisa chisimbiso maapplication.
Desmodur RE inoshandiswawo mukugadzira polyurethane elastomers. Polyurethane elastomers inoratidzira yakanakisa mechanicha zvinhu senge yakakwira elasticity, kubvarura kuramba uye abrasion kuramba. Iwo anoshandiswa mumaindasitiri akadai seshangu, mota nekugadzira maindasitiri. Desmodur RE inoita basa rakakosha mukubatanidzwa kweaya elastomers, ichivapa yakanakisa tensile simba uye elongation zvivakwa.
Uyezve,Desmodur REinozivikanwa nekukasika kurapa zvinhu. Izvi zvinoreva kuti inogona kukurumidza kuyambuka-yakabatana nema polyols kuita yakasimba polyurethane network. Kurapa nekukurumidza kunodiwa zvakanyanya mumaindasitiri anoda kukurumidza kuchinja nguva, senge mota kana maindasitiri ekuvaka. Uye zvakare, Desmodur RE ine kuenderana kwakanaka neyakasiyana siyana polyols, zvichiita kuti vagadziri vagadzirise zvivakwa zvezvigadzirwa zvavo kune zvakanangana nezvinodiwa.
Mukupedzisa, Desmodur RE (CAS 2422-91-5) isanganiswa inoshandiswa zvakanyanya ine mashandisirwo akafara mumaindasitiri akadai semachira, anonamira uye elastomers. Hunhu hwayo hwakasiyana, zvinosanganisira kuomeswa kwakawedzera, kunamatira uye nekukurumidza kurapa, inoita kuti ive sarudzo yakakurumbira pakati pevagadziri. Kunyangwe ichipa corrosion dziviriro kuburikidza ne polyurethane coatings, kuwana ma bond akasimba mumanamira, kana kusimudzira ma mechanic properties ye elastomers, Desmodur RE yakaratidza kuva chinhu chakakosha mukugadzirwa kwepamusoro-performance zvinhu.
